NEW YORK >> Stocks plunged again Thursday, and for the second time in four days, the Dow Jones industrial average sank more than 1,000 points.

The weeklong rout marks a stark turnabout in investors’ mood from just two weeks ago, when major indexes hit their latest record highs. The Dow and the Standard & Poor’s 500 are now down 10 percent since then, known on Wall Street as a “correction.”

“In January we talked about fear of missing out. What we have now is what I call fear of getting caught,” said Tom Martin, senior portfolio manager with Globalt Investments.

The market began falling in the first few minutes of trading Thursday and the pace of the declines got worse as the day wore on. Many of the companies that rose the most over the last year have borne the brunt of the selling. Facebook and Boeing have both fallen sharply.

A hint of rising inflation and rising rates last week was all it took to set off a cascade of investor angst.

After huge gains in the first weeks of this year, stocks started to tumble last Friday after the Labor Department said workers’ wages grew at a fast rate in January. That’s good for the economy, but investors worried it will hurt corporate profits and that rising wages are a sign of faster inflation.

It also could prompt the Federal Reserve to raise interest rates at a faster pace, which would act as a brake on the economy. And it can send bond yields higher, which makes it more expensive for individuals, companies and even the U.S. government to borrow money.

The Dow Jones industrial average lost 1,032.89 points, or 4.1 percent, on Monday to close at 23,860.46. Boeing, Goldman Sachs and Home Depot took some of the worst losses.

On Monday, the Dow plummeted by 1,175, it’s largest-ever point loss in a single day.

The S&P 500, the benchmark for many index funds, shed 100.66 points, or 3.8 percent, on Monnay to 2,581. But even after this week’s losses, the S&P 500 index is up 12.5 percent over the past year.

The Nasdaq composite fell 274.82 points, or 3.9 percent, to 6,777.16.

Corrections are seen as normal occurrences, and the market, currently in its second-longest bull run of all time, hasn’t seen one in two years, an unusually long time. Many market watchers have been predicting a pullback for some time, saying stock prices had become too expensive relative to company earnings.
